Well... Kinnikuman at first wasn't about wrestling, but later became entirely about superheroes fighting supervillains on the ring, and it is GLORIOUS xD
If you like wrestling, Shounen anime and creative character designs, you're going to love Kinnikuman, because the heroes and villains are all bonkers in the design and powers department. One of my favorite examples is Sneagator, a crocodile man with the powers of a sneaker, and his grandson MAXman (or Pumpinator in the Ultimate Muscle dub), who is just a shoeman with no crocodile powers xD
Recently there's a new anime on Netflix, Kinnikuman: Perfect Origin Arc, which is a sequel to the original anime/manga from the 80's. It's pretty good, and it starts with a episode recapping the original story's events, but I would recommend reading the manga because man... THE FIGHTS ARE SO FREAKING COOL!
There's also Kinnikuman Nisei, also known as Ultimate Muscle here in the west, it is a sequel series taking place several years after Kinnikuman, starring Kinnikuman's son, Mantaro (or Kid Muscle in the dub). It is a good anime/manga as well, but the anime is censored compared to the manga, and it's not just because 4Kids did the dub, the manga was... pretty violent at some points, so the anime toned it down to make it less violent for the kids.
Fun fact: Kinnikuman Nisei was so popular in the west that, after it ended with a filler arc, 4Kids themselves asked for more episodes! And thanks to 4Kids, we got two more seasons of Kinnikuman Nisei, which covered more of the manga. I don't like 4Kids for a lot of reasons, but this was one of the very few moments I can actually say "THANKS 4KIDS!" without a hint of irony.
